## Why history_search is rated Low

This tool searches and retrieves collaboration history records. It has no side effects, does not execute code, does not modify data, and does not delete anything. It is a pure Read operation that queries existing historical data. The low severity reflects minimal risk from misuse—exposing historical records poses no direct operational harm, though minor information disclosure concerns may apply in sensitive contexts.

From the tool's own definition: "Tool name 'history_search' and description '搜索协作历史记录' (search collaboration history) indicate a search/query operation that retrieves historical records without modifying or executing operations."

## Use case

AI agents call history_search to retrieve information from Claude Team MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
